20 Jan 2009 Computer generated holographical reference objectives for quality control of aspherical and spherical surfaces as well as optical systems. Software support for closed loop asphere manufacturing. Specifications
* CGH-diameter up to 300 mm
* Mounted in standard bajonetholder
* CGH with intergrated generation of the reference wavefront (similar to standard Fizeau transmission spheres).
* Integrated adjustment hologram for the lens under test
* Measuring precision PV < l/10
* CGH F-Number down to F/#=1.0 (amplitude CGH) and F/#=1.5 (phase CGH)
* For smaller F-Numbers, we offer conventional CGHs.
Characteristics
* Easy adjustment of the lens under test by means of the integrated adjustment hologram
* High measuring precision, no disturbances by the glass substrate
* No need of adjustment of the hologram relative to the interferometer
* No need of a separate holder for the hologram |
